Abstract: The wavelength conversion member includes: a first substrate; a second substrate; and a wavelength conversion layer disposed between the first substrate and the second substrate and including quantum dots which are excited by excitation light to emit fluorescence. The wavelength conversion layer is a cured layer obtained by curing a polymerizable composition which includes the quantum dots and a polymerizable compound having a molecular weight of 200 or lower, and the number of bubble-shaped defects having a diameter of 0.1 mm or more in the wavelength conversion layer is less than 10 per 100 cm2.

Abstract: Provided is manufacturing method of a quantum dot-containing laminated body including: forming a coating film by applying a quantum dot-containing composition which contains quantum dots, a curable compound, and a thixotropic agent and has a viscosity in a case of a shear rate of 500 s−1 of 3 to 100 mPa·s and a viscosity in a case of a shear rate of 1 s−1 of equal to or greater than 300 mPa·s, onto a first base material; laminating a second base material onto the coating film; and applying external stimuli to the coating film sandwiched between the first base material and the second base material for hardening, and forming a quantum dot-containing layer. The manufacturing method realizes high productivity, obtains a quantum dot-containing layer without coating streaks, and has slight film thickness unevenness of the quantum dot-containing laminated body.
